How to Play an AI RPG With Friends (2026): Every Multiplayer AI DM Compared
Most AI roleplay is built for one person. The whole category grew out of solo play — one player, one model, one story — and the multiplayer features arrived later, bolted onto products that were designed for an audience of one. That history matters, because it explains why “can I play this with my friends?” has such wildly different answers depending on which platform you ask.
A multiplayer AI RPG is any platform where several players share one AI dungeon master and one persistent world. The AI runs the game; the humans are all players. That is the crucial difference from a virtual tabletop, where one human still runs the game and the software just holds the maps.
We’ve reviewed every platform below first-hand. This guide sorts them by the thing that actually determines whether your group will still be playing in a month — not feature count, but how your group is expected to show up.
The Three Shapes of Multiplayer AI RPG
Before any rankings, the useful split. Group AI RPGs come in three shapes, and picking the wrong shape is why most group campaigns quietly die:
- Synchronous — everyone plays at the same time, like a real session. Highest energy, hardest to schedule.
- Asynchronous — players take turns across hours or days. Survives adult life, loses the live-table buzz.
- Discord-native — the game lives in a server you already use. Lowest friction, fewest features.
Almost every group that fails does so because they picked a synchronous platform and then never managed to synchronise. Be honest about which shape you are before you look at feature lists.
1. Friends & Fables — Best Overall Multiplayer AI RPG
Friends & Fables (3.9) is the most complete multiplayer AI tabletop available, and the only one that genuinely feels like it was designed for a party rather than adapted for one. It supports up to six players, and its combat is real tactical combat: hex battlemaps with line-of-sight, cover, and resistance calculations, not narrated abstraction.
The reason it holds up across a long group campaign is architectural. Its AI game master, Franz, isn’t a single model — player actions route to up to a dozen specialised models in parallel, one handling lore retrieval, another the character sheets, another map coordinates. And its Working Context system builds a transparent, player-editable document before each response, filtering in only what’s relevant to the current scene. With six players generating six times the noise, that filtering is the difference between a world that remembers and one that doesn’t.
The cost is complexity and price. This is the most demanding platform here to learn, and the group tiers are the ones that unlock the higher player counts. Franz is also available as a Discord bot if you’d rather not migrate your group to a new platform at all.

2. Old Greg’s Tavern — Best Value for a Group
Old Greg’s Tavern (3.0) sits in the same territory as Friends & Fables — persistent long-session campaigns with real character sheets — with fewer rules, a rowdier voice, and one pricing decision that makes it the obvious pick for a budget-conscious group.
Invited friends play completely free. Only the host spends credits. A story of up to 50 rounds costs the host 5 credits, and up to five friends join at no cost to them. Every other synchronous platform here effectively charges per seat or gates group size behind a higher tier. This one charges one person.
If your group’s blocker is “I’m not asking four people to each pay a subscription for something we might play twice,” this is the answer to that specific problem. The trade-off is fewer mechanical guardrails than F&F and a deliberately edgier tone that won’t suit every table.

3. Infinity DM — Best for Groups That Can’t Schedule
Infinity DM (2.7) is free, and it is the only platform on this list that treats scheduling — not memory, not mechanics — as the core problem worth solving.
The premise is blunt: adult campaigns don’t die because the rules were bad. They die because five people could not agree on a Tuesday. So Infinity DM is built around asynchronous, persistent group play. You take your turn today. Someone else takes theirs tomorrow. The campaign advances at the speed of the group’s actual lives rather than the speed of its calendar.
It is mechanically lighter than Friends & Fables and it will never give you the buzz of a live table. But a mechanically lighter campaign that is still running in three months beats a tactically rich one that collapsed after session two — and for most adult groups, that is the real comparison.

4. Taverna — Best If Your Group Already Lives on Discord
Taverna runs a full D&D 5e game master inside your existing Discord server. Invite the bot, set up a channel, start with a slash command. No new accounts, no new app, nothing for your group to learn.
That friction argument is stronger than it sounds. Adopting a new AI RPG platform rarely fails on features — it fails on convincing five adults to each make an account, learn an interface, and commit to trying something unfamiliar together. Taverna removes that step entirely. The mechanical automation underneath is genuinely capable: initiative tracking, combat management, group inventory, and levelling, all running behind ordinary Discord messages.
The honest trade-off is that a Discord text channel is not a battlemap. Spatial tactics are abstracted into narration. For socially-driven groups that’s no loss; for tactical ones it’s disqualifying. Taverna is currently in closed beta (invite only), so we haven’t assigned it a rating — we don’t rate pre-release platforms.

5. AI Dungeon — Best for Freeform Group Chaos
AI Dungeon (2.6) has supported multiplayer longer than almost anything else here, and it remains the pick when your group wants story, not system. There are no character sheets to respect and no rules to enforce — just a shared world that goes wherever the party pushes it.
Its most underrated group feature: the host can act as a supervising dungeon master, editing and fixing the AI’s responses as they come. That single capability solves the biggest weakness of AI-run group play — when the AI misreads the scene, a human can quietly correct it instead of the whole table losing the thread.
The limits are the familiar ones: in-context memory that doesn’t hold across a long campaign, and a small free-tier context window. Great for a wild weekend one-shot; weaker as a year-long campaign engine.

6. The Rest of the Field
AI Realm (2.3) is the rules purist’s option — genuine 5e character creation, real rule enforcement, automated combat math — with expanded multiplayer on its higher tiers. Its in-context memory degrades over long campaigns, so it suits contained arcs better than epics. Review.
FableAI (2.4) is the best-produced mobile option we’ve tested, with co-op multiplayer alongside voice narration and generated art. The gem economy is the catch — the polish is real, and so is the pressure to pay for it. Review.
Voyage, Latitude’s structured successor to AI Dungeon, supports synchronous co-op for up to four players with shared permadeath — the whole party carries the consequences together, which is a genuinely distinctive group dynamic. It’s in invite-gated expanded beta with an open beta planned later in 2026, so it carries no rating yet. Review · vs AI Dungeon.
RoleForge is worth flagging for the opposite reason: despite its excellent database-backed memory, it has no co-op multiplayer yet. It’s on the roadmap, not shipped, and play is currently solo with AI-controlled party members. Don’t pick it for a group today. Preview.
AIDungeonMaster.ai claims multiplayer for up to five in a 5e engine, but it’s application-gated early access with promotional numbers we could not verify — we’d wait for open access. Review.

What Actually Breaks in Group AI Play
Multiplayer AI RPGs fail in ways solo play never does, and knowing them in advance is most of the fix:
- Memory degrades faster. Every player adds text to every scene. A context window that comfortably held a 40-turn solo campaign hits its wall far sooner with five people in the room. This is why database-backed memory matters more for groups than for solo players — and why our guide on why LLMs forget is worth ten minutes before a long campaign.
- Spotlight drift. The AI tends to respond most to whoever wrote most. Quiet players get narrated past. A human DM corrects for this instinctively; an AI needs to be told, explicitly, to give each character a beat.
- Turn collision. In synchronous play, two players acting simultaneously can produce a response that contradicts one of them. Groups that agree on a simple turn order in advance have far fewer of these.
- One person carries the setup. In practice a single member does the configuration and becomes the de facto host. Platforms with host-pays pricing acknowledge this honestly; others quietly assume it.
For long group campaigns, the practical fix to the first problem is deliberate compression: our free Campaign Memory Tool tracks shared world state outside the chat, and how to summarise a long campaign covers the technique.

Frequently Asked Questions
Can you play an AI RPG with friends?
Yes. Several AI dungeon masters support multiplayer directly. Friends & Fables handles up to six players with tactical battlemaps, Old Greg’s Tavern lets a host bring in up to five friends who play free, Infinity DM runs asynchronous group campaigns, and Taverna runs a D&D 5e game inside a Discord server. The main choice is whether your group plays at the same time or takes turns across days.
What is the best multiplayer AI dungeon master in 2026?
Friends & Fables rates 3.9/5 and is the most complete of them. It supports up to six players, runs hex battlemap combat with line-of-sight, and uses a Working Context memory system that keeps long campaigns coherent. It asks the most of your group in setup and cost, so it suits people who want a genuine virtual tabletop rather than a casual session.
Is there a free multiplayer AI RPG?
Infinity DM is free and built specifically for asynchronous group play. Old Greg’s Tavern is the cheapest way to run a synchronous group, because invited friends play at no cost and only the host spends credits. AI Dungeon has a free tier that supports asynchronous multiplayer, though the free tier’s context is small.
How do you play D&D with AI and friends?
For rules-faithful 5e with a group, AI Realm and Friends & Fables both enforce real mechanics, and Taverna runs 5e inside Discord. Friends & Fables goes furthest on tactical combat with hex maps and line-of-sight. If your group cannot agree on a time, Infinity DM is built around asynchronous turns instead of live sessions.
Can an AI dungeon master handle a whole party at once?
It can, but it is genuinely harder than solo play. The AI has to track several characters, remember what each one did, and give everyone spotlight time, and most in-context memory systems degrade faster with more players because every turn adds text. Platforms that store state outside the context window, like Friends & Fables, hold up better across a long group campaign.
What is asynchronous AI RPG multiplayer?
Asynchronous multiplayer means players take their turns whenever they can rather than meeting for a live session. You post your action today, another player posts tomorrow, and the AI narrates the results as they come in. Infinity DM is built entirely around this model, and AI Dungeon supports it too. It solves scheduling, which is the reason most adult campaigns actually die.
